Abstract

The method comprises the following steps: a) lixiviation; b) solid-liquid separation; c) neutralization of the aqueous solution; d) solid-liquid separation of the zinc-rich solution; e) zinc extraction; f) purification of the organic solvent from the extraction step; g) re-extraction of the ionic zinc charged in the organic solvent; h) recovering the zinc contained in the acid aqueous solution from the re-extraction step. The following barriers for impurities have been established: soft lixiviation; alkaline pulp treatment;
treatment of a small flow of the aqueous solution removed before and/or after the zinc extraction step e); high selectivity of the dissolved zinc extraction; treatment of the zinc charged in the organic solvent; treatment to clean the zinc-charged organic solvent with an ultra-pure acid solution;
partial purging and treatment of the re-extracted organic solvent; purging a small flow from the cycle for obtaining the final product that will be recycled in the organic cycle.
